Here are a few types of pipe tube bending.
1. Wiper Dies
In extreme situations, when a thin tube needs a tight bend, a wiper die may be needed. The wiper is inserted into the grove between the tube and the bending die to prevent a wrinkle defect due to uneven internal wall compression.
2. Mandrel Functions
A Mandrel is less a method of tube bending and more an aid to pipe bending in Australia. As a piece of tube is bent, the external wall of the tube necessarily thins. This comes with a tightening of the bend radius and an increased chance of a flattened bend. To counter this, a device called a mandrel sometimes put inside the tube at the point of the bend. This offers support and increases the chance of getting the desired shape when bending.
3. Roll Bending
Roll bending can be good for circular fabrications, such as wheel rims.
It involves the use of a machine with three rollers, called a jig. Roll bending can be used to bend both metal bars and sheet metal. It works by putting the bar into the jig and manually lowering and pressing the middle roller against the bar. As the rollers are rotated, the bar moves along, and force is applied to the bar as it goes back and forth along the rollers until it reaches the desired shape.
4. Rotary Draw Bending
Rotary draw benders allow for more specific jobs and are used to bend tube and pipe for products like roll cages, handrails, and handles. And so it is called as a more precise type of bending. This type of bending uses a rotary draw machine that bends the metal through a series of die sets with a consistent centre line radius.
5. Press Bending
Press bending is one of the easiest and most common types of tube bending. This process involves pressing a â€śbend dieâ€ť against the pipe to force it to conform to the shape of the bend.
